If you get bit by a poisonous snake, which make it good to know what snakes are poisonous and which aren’t (you will have to research this on your own time), make sure you wash it with soap and water, keep the area lower than your heart, wrap above the bite to help slow the venom, and don’t try to suck the venom out.
If you find yourself in cold water, put on your life jacket and float on your back. If you can’t float on your back, then tread water slowly, and if you can’t tread water, try to find something buoyant including your shirt filled with air. Don’t swim because increased activity won’t keep you warm.
If you find yourself outside for a long time in cold weather (not water), the first layer should draw moisture off your skin, the second layer should trap warmth to your body, and the third layer should allow moisture out but not in. For example, long underwear, parka, and jacket.
If you find yourself in a tunnel fire, phone for help, stay in car if you can breathe easily, get out of car if it becomes hard to breathe, and try to exit but do not prop emergency exit doors.
If you find a tick on a body, use a tweezers or credit cards to pull the tick away, clean the area about the bite, and put the tick in a container if you want to know if it has a disease. Back in the day, we just killed them and threw them away. By the way, ticks that have been feeding a long time are grey/silver in color on their fat bodies.
If you find yourself in a sword fight, don’t back away or extend your arm. Get in closer and block in the center of your sword. Keep your arms close to your body and push against the other sword when attacked.
